Well to all trying to get your display working it is possible. I have a 03 with the Ebay double din installed. I also put a 2008 information display in and it is fully functional with some creative wiring. Check out the pictures for the final install. PM me if you would like to know how to do it. The benefit is that the 2008 display allows for customization of the text as well as being a better design that is less prone to failure.
I would like to express my gratitude for this immense insight! Thanks to you I finally have my fan controls and temp displaying correctly on my MS6 LCD screen!!Pins 7&9 are the CAN bus which took me forever to figure out where to get this. This comes from the double din kit. The two pin connector with Pink and Blue/Pink. Pin 7 goes to the pink and pin 9 is blue/pink. This is what sends all the HVAC information to the display.
This should be all you need to get the information display working. Let me know if you have any more questions. Unlike many people who figure stuff out, I will actually stick around to answer questions and not keep it a secret. This took me about a month to finally figure out and I hope I can save you some time.
Any chance you'd be selling that dash kit in the near future?Kind of an old link... Messages from this thread were ESSENTIAL to my getting this to work on my wife's 2004 Mazda 6 Sport Wagon. Used a Pioneer single DIN Bluetooth Stereo, 2008 display, a Maestro kit for the steering wheel controls which all work. Phone works with bluetooth hands free. All air and other controls work fine. Only thing that didn't work out was for some reason by lights don't work on the shifter console. Think this is unreleated to the kit...
